INPE observes slowing deforestation with DMCii

Brazil’s National Institute for Space Research (INPE) has completed its August 2008-July 2009 detailed survey of deforestation by shallow cut throughout the Amazon region (INPE announcement). Its PRODES (Monitoring of the Brazilian Forest by Satellite) programme analyzed 400 images from Landsat, CBERS and the DMC Satellite Constellation to confirm that deforestation during the period was 7464 square kilometers, a reduction of 42% in comparison to 2007-2008. This is the lowest annual deforestation rate since INPE started systematic monitoring of the Amazon forest by satellite in 1988.
DMCii has worked with INPE to provide annual imaging of the whole Amazon Basin since 2005 to support this activity. By using multiple satellites, each capable of imaging a 650km wide swath of the forest canopy, DMCii is able to provide multi-spectral images of the entire area in 4-6 weeks. This provided INPE with valuable and timely information to help identify the extent of deforestation.

DMCii satellite images show illegal logging in Amazon rainforest

A significant decline in deforestation in the Amazon Basin has been observed since 2004. This is due in part to INPE’s new earth DETER system that detects deforestation in real time by fortnightly satellite imaging. This allows the supervisory board to take effective and prompt actions to combat illegal logging as it happens, rather than having to wait until after the damage is done.
Satellite capabilities play a crucial role in providing impartial information about deforestation in these large, inaccessible areas. The development of satellite constellations, pioneered by the DMC satellite constellation, has led to improved temporal and spatial resolution, enabling operational monitoring to support active and timely response to deforestation.
